CHANNEL-BRICK.

Specification of Letters Patent.

Application filed July 8, 1916. Serial No. 108,190.

like letters on the drawings representing like parts.

My present lnvention is an improved form of channel brick intended for use in building construction, wherein an extremely simple and economical brick of this type is desired. In my prior application, SerialNo. 871,271, filed November 10, 1914, which has matured into Patent No. 1,304,552, dated May 27, 1919, I have shown and described a type of channel brick adapted for my novel form of Twin wall construction, and 1n my prior application, Serial No. 826,099, filed March 20, 1914, I have also shown a specific form of interlocking channel brick. Also, in my copending application, Serial No. 108,159, filedJuly 8, 1916, which hasmatured into Patent No. 1,377,572, dated May 10, 1921, I have illustrated and described a further form of cored channel brick. My present brick and the wall structure built therefrom contains certain of the interlocking features and advantages of my said prior application, Serial No. 826,099, together with certain of the advantages and features ofmy said copending application on cored channel brick. The improved channel brick of my present invention is of simpler form more economical to make, out and transport and with less danger to damage or injury during transportation, or building, having practically no projecting rib portions to be damaged. Referring to the drawings illustrating two forms of the invention,

iguresl and 2 upon one form, illustrate in cross section of a single or completed channel brick, and a perspective fragmentary view of a wall structure made therefrom and retain a substantial mass of mortar in each wall section, while preserving a horizontal, open air space, interrupting the mortar course, is an important feature to both forms of channel brick illustrated in the drawings. Each form of the brick has wall sections comprising inner and outer vertically extending ribs 2 and 3, united in the brick of Fig. 3 by a body portion or tie member 1, and in the brick of Fig. 1, by the vertical ribs 4 and 5 and cross member 6, both vertical ribs and cross member being formed integrally with the horizontal body portions 7. and 8 of the wall sections. In each form of channel brick, also, the vertical rib-like members 2 and 3 are united at their outermost-ends, by webs 9 and '10, which present a broad mortar bearing surface sufiicient to receive and retain a mortar layer on their upper surfaces, when the brick is built into a wall with the tie member in its lowermost position, as shown in Fig. .4, or to act as a bearing for the brick upon the mortar course, with the tie member in topmost position, as shown in Fig. 2. Both types of channel brick maintain the central, open, horizontal, channel-like air space throughout the wall for moisture-proofness, interrupting the horizontal mortar course 11, 11, as in Fig. 4, and 12, 12, as in Fig. 2, in the latter case the additional moisture-proof feature of the raised cross-rib 6 being presented, the

mortar courses 12 butting against the verti- 1 brick and the finished wall has the appear ance of a solid brick wall, while affording a very light construction, easily and quickly I laid, and very economical in mortar.

The wall constructed from this type of channel brick is very light in weight, economical in mortar used, and can be quickly laid up, the width of the channel brick being preferably the entire thickness of the wall and presenting a finished appearance .on each side.

My present invention is further described and defined in the form of claims as follows:

1. A channel brick of the kind described, adapted as a building unit for hollow twin wall structures, said brick comprising two cored wall sections, each section having vertical outer and inner riblike webs, the outer Web being of substantially standard brick size in area, each section forming a j mortar seat and both sections being united by a horizontal body portion at one side of said vertical wall sections, the wall sections and uniting portion forming an open channel to interrupt the mortar course, and said wall sections and body portion being of substantially uniform thiclmess.

2. A channel brick of the kind described adapted as a building unit for hollow twin wall structures, said brick comprising two cored wall sections, each section having vertical outer and inner riblike webs, the outer web being of substantially standard brick size in area, each section forming a mortar seat and both sections being united by a horizontal body portion at one side of said vertical Wall sections, said body portion projecting from said wall sections to limit and define the mortar seat over the edge of each section and constituting an interruption for raooaoe the mortar course and a moisture check and interlock. r

'3. Hollow wall construction of channel brick comprising twin walls and an internal horizontal air space, each twin wall consisting in hollow wall" sections having vertically extending inner and outer sides, the outer side of the brick constituting the exposed face of the wall, and providing substantial mortar seats for the wall sections in each side wall, said wall sections being united by a body portion projecting above the mortar seat of each wall section adjacent thereto and constitutinga mortar defining ridge, interrupting the mortarcourse and interlocking therewith.

In testimony whereof, I have signed-my name to this specification, in the presence of two subscribing witnesses.
